Louis Tomlinson's Sister Félicité Tomlinson Dead at 18

According to the site, the former One Direction member’s sister died after suffering a heart attack. TMZ reports that Félicité passed away on Wednesday, March 13, at her apartment in London. She reportedly collapsed and was unable to be revived by paramedics.

Félicité was a model and fashion designer with a 1.3 million following on Instagram. According to reports, she had plans to publish a poetry book.

The tragic news comes after Louis lost his mother to cancer in December 2016. His mom, Johannah Deakin, was just 43. The singer, who is the eldest of 7 siblings, recently released a heartbreaking song dedicated to his mother called "Two of Us.”

Louis has since pulled out of a performance on a BBC charity show called Comic Relief.

Our thoughts and prayers go out to Louis, his family and all those affected.
